NAME
       ldns-keyfetcher - retrieve the DNSSEC DNSKEYs for a zone

SYNOPSIS
       ldns-keyfetcher [ OPTIONS ] DOMAIN

DESCRIPTION
       ldns-keyfetcher is used to retrieve the DNSKEYs of a zone.

       First it finds all authoritative nameservers of the zone by tracing it from the root down.
       All authoritative nameservers are then queried (using TCP) for the  DNSKEY  RRset  of  the
       zone apex. If the results are all the same, the key resource record set is printed.

OPTIONS
       -4 Only use IPv4

       -6 Only use IPv6

       -h Show a help text and exit

       -i  Insecurer mode; there will only be one query for the DNSKEYS. There will not be cross-
       checking of all authoritative nameservers.

       -v verbosity

       Set the verbosity level. The following levels are available:

	0: default, only print the DNSKEY RRset found, or an error on failure.
	1: Show the nameservers that are queried
	2: Show more info on what is checked
	3: Show the intermediate results (authority and dnskey rrsets)
	4: Print the answer packets that are returned

       -r file

       Use file as the root hints file, should contain A  records  in  presentation  format.  The
       default	 is   /etc/named.root.	 You   can   get   this   file	 from	http://www.inter-
       nic.net/zones/named.root.

       -s Don't print the keys to stdout, but store them in files.

       The filenames will be of the format K<file>.+<alg>.+<keytag>.key
